Also keep steps down to 5Khz for best resolution. It is very very important to keep you Sweep widths to less than 6M 6 Mhz wide for the band scope to be very useful. Hold is the key which is very important here. Running the bandscope continuously has very little utility so keep in mind you need to be able to know when to hold em. So now you have some Custom searches programmed in and assigned bansdcope operation to Key 3. These are two different settings (Custom Search settings and Bandscope Key Settings). Button 3 is highly recommended and may not be optional in the 396xt. You need to assign the band scope mode to keys 1,2 or 3. It is scan/search mode they talk about in the documentation. If they are not locked out the radio will during scan mode will find them and start a search on them which can be confusing. Make sure you keep them locked out or you will have mess on your hands. Each one assigned to front panel key 0-9. You are allowed I think 10 custom searches. Choose one or two to put aside for your bandscope work. To gain better control, program some custom search frequencies in the custom section. My observation shows band scope uses the frequency to sweep based on what you are scanning or searching at the time. You need to spend a little time to set this radio up so band scope works predictably well. I also am not sure which IF they are using Sweeping 1st or 2nd, 3rd ? May be all depending what band you are in. Don’t confuse bandwidth for Steps or Sweep start and stop width. I would guess the bandwidth would be similar to the modulation with FM,WFM,NFM. The bandwidth filter being used to pick up that energy is unknown again because it is not published. The Band Scope Sweeps IF (Intermediate Frequency Amplifier) is swept for energy detection in the spectrum. First let me say I do not know the full limitations or specification of its capability because Uniden did not publish any data on it. It can be used to make ruff measurements of electrical emissions in a screen room. What Uniden calls Band Scope is actually a simple spectrum analyzer and it appears to work very well. I don’t think the people over there get it and Uniden did not document it very well. I could not get Band Scope working properly using Butels’a ARC XT Pro Software. Unfortunately they do not have enough code in the firmware AND FRONT PANEL KEYS so as to make it easy to operate. The Band Scope Feature is very popular with amateur radio operators so I suspect that this is why they decided to put this feature in the BCD996XT.
